Sandbox Environment Purpose

What This Environment Does

Runs all 22 Pass 22 deterministic gates in exact production order
Connects to real broker sandbox API for live market quotes
Submits test orders that receive genuine broker acknowledgements
Validates execution pipeline before ControlledLiveAuthorization
Generates SandboxExecutionReceipts as certification evidence
Tests all P0 safety gates against real broker sandbox responses

What This Environment Does NOT Do

Submit orders to live production broker accounts
Risk real capital — sandbox accounts only
Bypass any deterministic safety gate
Grant ControlledLiveAuthorization automatically
Simulate gates — all 22 run in exact production logic
Allow LIVE_EXECUTION_ALLOWED to become true
